Overclocking

Note: CPU-Z was not reporting voltage accurately for my testing of the ASUS ROG STRIX Z490-E Gaming. Power consumption numbers in the my testing are still accurate as they were measured outside of the software. I also verified that the board was accurately applying the voltage set in the BIOS using ASUS's software suite.

The ASUS ROG STRIX Z490-E Gaming showed a fair bit of headroom for overclocking, at least for short runs of wPrime. I was able to achieve 5.3 GHz at 1.38 V core voltage. However, longer runs were not stable. Overclocking is largely limited by temperature, as the 10 core Intel Core i9-10900K will overpower any ambient cooling solution. Depending on settings, the system will either crash or severely drop frequency.




For memory overclocking, the ASUS ROG STRIX Z490-E Gaming did well, reaching 4000 MHz at XMP timings and voltages on my Trident Z Neo kit. However, to pass my MemTest 64 validation without errors, I had to reduce the speed to 3900 MHz.
